Installation

In this manual, "User" refers to whoever has access to the Network Camera, and

"Administrator" refers to the person who can configure the Network Camera and grant

user access to the camera.

Hardware installation

Please verify that your product package contains all the

accessories listed in the foregoing Package Contents.

Depending on the user’s application, an Ethernet cable

may be needed. The Ethernet cable should meet the specs

of UTP Category 5 and not exceed 100 meters in length.

Upon powering up, the device runs through a self-test procedure and the front LEDs will

blink between green and red a few times. If self-test passes, the LED will be green and

the Network Camera will standby for getting IP address. After getting IP Address, the LED

will blink green every second. If self-test fails the red LED will blink several times. Refer

to Appendix A for troubleshooting.

The Network Camera will first detect Ethernet. If it does not connect to Ethernet, the

Network Camera will try WLAN. During the searching and connecting process to the

wireless access point or station, the red LED of the Network Camera will flash every

second. Until the Network Camera connects to the other wireless device, the red LED

will become lighted. Operating in either network mode, the green LED will flash every

second as heartbeat to indicate alive.

Connect the power adapter jack to the Network

Camera before plugging in to the power socket. This will

reduce the risk of accidental electric shock.

To install in Ethernet

Make sure the Ethernet is firmly connected to a switch hub. After attaching the Ethernet

cable plug in the power adapter. If the LED turns out to be steady green after self-test, go

to next paragraph “Software installation”. If the Ethernet is not available, Network

Camera will switch to wireless LAN mode.

To install in wireless LAN

If the Ethernet is not available while power on, the Network Camera will search for any

access point with the SSID “default”. Once any access point is found, the LED will turn

green to wait for installation. If the network environment cannot meet the default

settings, install Network Camera in Ethernet to proceed with wireless LAN configuration.

Software installation

At the end of the hardware installation, users can use Installation Wizard program

included in the product CDROM to find the location of the Network Camera. There may be

many Network Cameras in the local network. Users can differentiate the Network

Cameras with the serial number. The serial number is printed on the labels on the carton

and the back of the Network Camera body. Please refer to the user’s manual of

Installation Wizard for detail.

Once installation is complete, the Administrator should proceed to the next

section "Initial access to the Network Camera" for necessary checks and

configurations.

Initial Access to the Network Camera

Check Network Settings

The Network Camera can be connected either before or immediately after software

installation onto the Local Area Network. The Administrator should complete the

network settings on the configuration page, including the correct subnet mask and IP

address of gateway and DNS. Ask your network administrator or Internet service

provider for the detail information. By default the Network Camera requires the

Administrator to run installation every time it reboots. If the network settings are to

remain unchanged, disable the Install option. Refer to “Network settings” on the

System Configuration page for details. If any setting is entered incorrectly and cannot

proceed to setting up the Network Camera, restore the factory settings following the

steps in the “Troubleshooting” chapter of the Appendix.

Add Password to prevent Unauthorized Access

The default Administrator’s password is blank and the Network Camera initially will not

ask for any password. The Administrator should immediately implement a new

password as a matter of prudent security practice. Once the Administrator’s password

is saved, the Network Camera will ask for the user’s name and password before each

access. The Administrator can set up a maximum of twenty (20) user accounts. Each

user can access the Network Camera except to perform system configuration. Some

critical functions are exclusive for the Administrator, such as system configuration, user

administration, and software upgrades. The user name for the Administrator is

permanently assigned as “root”. Once the password is changed, the browser will

display an authentication window to ask for the new password. Once the password

is set, there is no provision to recover the Administrator’s password. The

- 8 -

only option is to restore to the original factory default settings.

How to Use

Authentication

After opening the Web browser and typing in the URL of the Network Camera, a

dialogue window pops up to request a username and password. Upon successful

authentication, the following figure is displayed.

The foreground is the login window and the background shows the message if

authentication fails. The user may check the option box to save the password for future

convenience. This option is not available to the Administrator for obvious reason.

Installing plug-in

For the initial access to the Network Camera in Windows, the web browser may prompt

for permission to install a new plug-in for the Network Camera. Permission request

depends on the Internet security settings of the user’s PC or notebook. If the highest

security level is set, the computer may prohibit any installation and execution attempt.

This plug-in has been registered for certificate and is used to display the video in the

browser. Users may click on

to proceed. If the web browser does not allow the

user to continue to install, check the Internet security option and lower the security

levels or contact your IT or networking supervisor for help.

Digital Zoom

Click on the magnifier icon under the camera view then the digital zoom control panel

will be shown. Uncheck “Disable digital zoom” and use the slider control to change the

zoom factors.

- 12 -

Snapshot

Click on “Snapshot”, web browser will pop up a new window to show the snapshot.

Users can point at the snapshot and click the right button of mouse to save it.

Client settings

At the initial access to the “Connection type” page in Windows, the web browser will ask

for a new plug-in installation, the plug-in being the Network Camera. This plug-in has

been registered for certification and can be used to change the parameters at the

client’s site. The user may click on

to install the plug-in. If the web browser

does not allow the user to complete the installation, check the Internet security to

- 13 -

lower the security level or contact your IT or networking supervisor.

There are two settings for the client side. One is “Media Option” for users to

determine if audio should be muted. The other is “Protocol Option” which allows

choices on connection protocol between client and server. There are three protocols

choices to optimize your usage - UDP, TCP and HTTP.

The UDP protocol allows for more real-time audio and video streams. However, some

packets may be lost due to network burst traffic and images may be obscured.

The TCP protocol allows for less packet loss and produces a more accurate video

display. The downside with this protocol is that the real-time effect is worse than that

with the UDP protocol.

The HTTP protocol must be selected if the network is protected by a firewall and it only

allows HTTP Port (80) to be opened. In this mode, audio will not be sent and only video

is operational. If no special need is required, UDP protocol is recommended. Generally

speaking, the client’s choice will be in the order of UDP → TCP → HTTP. After the

Network Camera is connected successfully, “Protocol Option” will indicate the selected

protocol. The selected protocol will be recorded in the user's PC and will be used for the

next connection. If the network environment is changed, or the user wants to let the

web browser to detect again, manually select the UDP protocol, save, and return HOME

- 14 -

to re-connect.

<url>

http://<Network Camera>/protocol.html

<Network Camera> is the domain name or the original IP address of the Network

Camera.

Fine-tuning for Best Performance

Best performance generally equates to the fastest image refresh rate with the best

video quality, and at the lowest network bandwidth as possible. The three factors,

“Maximum frame rate”, “Fix bit rate”, and “Fix quality” on the Video Configuration page,

are correlative to allow for achieving the best performance possible.

For Best Real-time Video Images

To achieve good real-time visual effect, the network bandwidth should be large enough

to allow a transmission rate of greater than 20 image frames per second. If the

broadband network is over 1 Mbps, set the “Fix bit rate” to 1000Kbps or 1200Kbps, and

set “Fix quality” at the highest quality. The maximum frame rate is 30. If your network

bandwidth is more than 384Kbps, you can fix the bit rate according to your bandwidth

- 16 -

and set the maximum frame rate to 30 fps. If the images vary dramatically in your

environment, you may want to slow the maximum frame rate down to 20 fps in order

to lower the rate of data transmission. This allows for better video quality and the

human eyes cannot readily detect the differences between those of 20, 25, or 30

frames per second. If your network bandwidth is below 384 Kbps, set the “Fix bit rate”

according to your bandwidth and try to get the best performance by fine-tuning with

the “Maximum frame rate”. In a slow network, greater frame rate results in blur images.

Another work-around is to choose “Half” in the “Size” option for better images, or

“Halfx2” for a larger image view. Video quality performance will vary somewhat due to

the number of users viewing on the network; even when the parameters have initially

been finely tuned. Performance will also suffer due to poor connectivity because of

the network’s burst constraint.

Only Quality Images Will Do

To have the best video quality, you should set “Fix quality” at “Detailed” or “Excellent”

and adjust the “Maximum frame rate” to match your network’s bandwidth. If your

network is slow and you receive “broken” pictures, go to the TCP protocol in

“Connection type” and choose a more appropriate mode of transmission. The images

may suffer a time delay due to a slower connection. The delay will also increase with

added number of users.

Somewhere Between Real-time and Clear Images

If you have a broadband network, set “Fix quality” at ”Normal” or better, rather than

setting “Fix bit rate”. You can also fix the bandwidth according to your actual network

speed and adjust the frame rate. Start from 30 fps down for best results but not below

15 fps. If the image qualities are not improved, select a lower bandwidth setting.
